Washington: Indian Nobel Peace Prize winner Kailash Satyarthi's "relentless work" and "peaceful struggle" to keep children in school, rather than in the workforce, has been highlighted in a new US report.

"For more than four decades, Satyarthi has worked relentlessly for the rights of children and waged a peaceful struggle to keep children in school, rather than in the workforce," said the US State Department's Trafficking in Persons Report 2015.
